ARH long tube headers long system for the 1999-2006 Chevy/GM Truck/SUV 4.8L/5.3L features 304 stainless steel 1 3/4" primaries, 3" merge collectors, and y-pipe along with all the necessary hardware and gaskets for a bolt-on installation.

The 1999-2006 Chevy/GM Truck/SUV 4.8L/5.3L American Racing Headers long systems were designed to bolt-on to your factory axle-back or any aftermarket axle-back. Some modification may be required. The American Racing headers require a crossover y-pipe assembly and they are offered with or without converters. Catted crossover pipes cause very little restriction and they help to control emissions.
